Microsoft has released a new feature for Office 365, allowing administrators to prevent users from sending emails to blocked addresses.
The feature, called Tenant Allow Block List, previously only prevented users from receiving emails from selected senders.
Microsoft is ready to start previewing the feature in July and it will be available to everyone in the same month.
The evolution of Office 365
With attack vectors such as phishing attacks remaining an extremely popular way to circumvent antivirus software and carry out identity theft, this isn’t the only feature promising increased security that Microsoft has been able to deploy in previous months on its flagship e-mail client. mail.
The company has also added a new layer of security to the Office 365 email service as it seeks to improve the integrity of incoming and outgoing messages.
Microsoft says the new protection, SMTP MTA Strict Transport Security (MTA-STS), a feature first announced in the second half of 2020, will address issues such as expired TLS certificates, issues with third-party certificates, or unsupported secure protocols.
We expect these features to pay dividends in terms of user security, because the announcement comes as Office 365 prices have increased across all industries.
Since March 15, 2022, Microsoft 365 Business Basic has increased from $5 to $6 per user per year, Microsoft 365 Business Premium has increased from $20 to $22, Office 365 E1 has increased from $8 to $10, Office 365 E3 went from $20 to $23, Office 365 E5 went from $35 to $38, and Microsoft 365 E3 went from $32 to $36.
It’s easy to see why Microsoft might be looking to increase the security of its email services, companies could be even more vulnerable than originally thought to email-based attacks, according to a recent study by BitDam.
